Hard skills are technical abilities that can be measured, such as programming abilities or software skills. They are acquired through education and experience. Soft skills are personality traits and interpersonal skills, such as communication skills, flexibility, and time management. Unlike hard skills, soft skills are difficult to quantify and are developed through interaction rather than formal education. Both hard and soft skills are important for jobs, but hard skills are more technical and job-specific, while soft skills define one's personality and ability to work with others.
